Comparative Study
[Local recurrence and survival rate after rectal cancer operations and multimodal therapy].
In the guidelines of the German specialist medical societies, postoperative chemoradiotherapy is recommended for rectal carcinomas in stages II and III. In the meantime, there are important study findings favoring preoperative radiotherapy as against postoperative irradiation. In the present unicentric study, the clinical results after preoperative irradiation and postoperative chemotherapy are to be determined. In period I, sandwich radiation without total mesorectal excision was applied. In period II, the treatment was developed further with exclusive preoperative radiation and total mesorectal excision. Since from 1994 the therapy regimen has changed with the introduction of total mesorectal excision and improved radiotherapy, the present study was carried out to check whether this has led to better results of therapy. ⋯ Total mesorectal excision, preoperative radiotherapy and postoperative chemotherapy can effectively influence the rate of local recurrences after rectal carcinoma operations (0-4.3% after a mean period of follow-up observation of 3.58 years). No appraisal can be made with regard to the benefit resulting from the individual measures.

Thoracic epidural anesthesia is increasingly being used in visceral surgery as an adjuvant to general anesthesia and, in addition, as a postoperative method of thoracic epidural analgesia (TEA). This method interrupts specifically nociceptive reflexes, increases the blood supply by blocking sympathetic activation, improves pulmonary function, and has a beneficial effect on gastrointestinal (GI) motility. ⋯ The combination of TEA and general anesthesia has been shown to offer advantages after operations on both the upper and the lower GI tract. The positive effects of the TEA in the postoperative period should be used for the early enteric nutrition and mobilization of patients.

A Nissen fundoplication for gastrooesophageal reflux disease may more often lead to persistent dysphagia than a Toupet fundoplication. The aim of this study was to assess the results of laparoscopic Nissen versus Toupet fundoplication in patients with reflux disease and impaired distal esophageal motility. ⋯ In patients with reflux disease and impaired distal esophageal motility, laparoscopic Nissen and Toupet fundoplication both yielded satisfactory results and neither operation led to increased dysphagia.

[The surgeon as a cost factor. Cost analysis exemplified by surgical treatment of rectal carcinoma].
Besides quality, costs play an increasingly important role. For rectal carcinoma, the cost of the surgical treatment of the disease (including after-care) was analysed under variable clinical conditions. ⋯ Costs as well as the patient's prognosis depend to a great extent on the quality of the procedure and consequently on the individual operating surgeon. A complicated course is associated with a considerable increase in costs. A complete cost analysis of rectal carcinoma has to include the cost of a potential locoregional recurrence which would lead to the additional prolonged after-care for these patients.

Comparative Study
[Long-term results in the surgical treatment of pilon tibial fractures. A retrospective study].
While Pilon fractures of the tibia have been treated for decades by primary open reduction and internal fixation by plate osteosynthesis, during the last 10 years differential treatment was developed: After primary open reduction nowadays patients are treated with (according to type of fracture and tissue damage). As well as primary open reduction and internal fixation a two-step treatment (primary external fixator and delayed ORIF) or consolidation by external fixator combined with minimal invasive osteosynthesis (cannulated screws and K-wires) has been implemented. Furthermore, the significance of primary bone grafting in comminuted fractures to prevent aseptic pseudarthrosis has been acknowledged. ⋯ The complication rate in the treatment of pilon fractures depends mainly on the type of fracture, the soft tissue damage and the type of treatment. The results of primary ORIF varied. In the case of low-grade soft tissue damage, good to excellent results were accomplished. In the case of higher-grade soft tissue damage, the problem of soft tissue coverage and reconstruction of the joint surface could be solved with good results by the two-step treatment. Herewith it is important to use limited open reduction of displaced fragments and fixation by cannulated screws and K-wires. We consider ORIF of the fibula necessary as stabilization of the second column of the ankle joint.
